Prov 15:22

“See here, 1. Of what ill consequence it is to be precipitate and rash, and to act without advice: Men's purposes are disappointed, their measures broken, and they come short of their point, gain not their end, because they would not ask counsel about the way. If men will not take time and pains to deliberate with themselves, or are so confident of their own judgment that they scorn to consult with others, they are not likely to bring any thing considerable to pass; circumstances defeat them which, with a little consultation, might have been foreseen and obviated. It is a good rule, both in public and domestic affairs, to do nothing rashly and of one's own head. Plus vident oculi quam oculus - Many eyes see more than one. That often proves best which was least our own doing. 2. How much it will be for our advantage to ask the advice of our friends: In the multitude of counsellors (provided they be discreet and honest, and will not give counsel with a spirit of contradiction) purposes are established. Solomon's son made no good use of this proverb when he acquiesced not in the counsel of the old men, but because he would have a multitude of counsellors, regarding number more than weight, advised with the young men.”

“Without counsel purposes are disappointed,.... If a man determines and resolves upon a matter, and at once hastily and precipitately goes about it, without mature deliberation, without consulting with himself, and taking the advice of others in forming a scheme to bring about his designs, it generally comes to nothing; see Luk 14:28; or "without a secret" (s) without keeping one; if a man divulges his intentions, it is much if they are not frustrated; so the Targum, "vain are the thoughts (or designs) where there is no secret;'' if a man makes no secret of what he designs to do, he is easily counterworked, and his purposes disappointed; but in the multitude of counsellors they are established; his purposes are, as in Pro 20:18; having the advice of others, and these many, he is confirmed that he is right in what he has thought of and purposed to do; and therefore goes about it with the greater spirit and cheerfulness, and is most likely to succeed, and generally does; see Pro 11:14.
